| Abstract: | The mainlobe peak to sidelobe peak ratio of a linear FM output signal can be increased by setting an amplitude weight function called Huming function, and the Doppler shift spectrum also can be broadened. In this paper, the basic characteristics of a linear FM signal weighted by Huming function are described and compared to those of FM signal weighted by Hamming function and Taylor function are. |

| Keywords: | Huming function mainlobe peak to sidelobe peak ratio Doppler frequency signal to noise ratio |
